This is a question that could make you link me to a dictionary, but I'm not sure if using “la vie attitude” is the proper way.
I'm looking for a phrase that represents someone's attitude to life as of his philosophy. Actually, I'm trying to translate this:

Montaigne has published his Essais explaining his philosohy and life attitude.

My solution:

Montaigne creés son Essais expliquant son philosophie et son attitude de la vie.

Please note that my English is not perfect as well, so I may be a bit wrong with the usage of attitude.
